The relationship between economics on the one hand and disciplines such as history, psychology, and sociology on the other is much disputed and seems to me a little like that of couples who live in a state of hostile dependence: they cannot live together but cannot live apart.
Are there rules of political economy such that if they are obeyed prosperity invariably and everywhere results? Or, of course, if disobeyed, impoverishment? Ought an economist to be more like a novelist in his understanding than a scientist?
I recently read an article by Barry Eichengreen, professor of economics and political science at Berkeley, about the Greek crisis, if a situation that has continued for years can properly be called a crisis. The article addresses the mistakes made by Greece. Amen to that: who wants to repeat mistakes?
